What would happen if the Dance and the earrings weren't the only things that were given to them by the first sun breather, what would happen if the Kamado family had yoriichi's nichirin blade. But not only that but what would happen if Tanjirou had learned the way of the blade and the dance of the sun at the age of 7.

Tanjiro comes home to find his entire family dead. He was later found by Giyuu and was sent to Urodaki to train to become a demon slayer. But after he got their he got dreams of someone with hanafuda earrings(Yorrichi) performing a breathing technique he heard him call sun breathing that looked very similar to his family dance. After he told Urodaki about this he immediately told Tanjiro about sun breathing and that only one person was able to do it. After seeing that Tanjiro cam actually use sun breathing he immediately told him to train and train more in this breathing technique. Over the next two years Tanjiro would get the same dreams and has learned how to perform the 12 moves flawlessly and is still training to do the 13 form. Read the first chapter for more information.

Instead of Giyuu tomioka finding Tanjiro, kyojuro Rengoku, the flame hashira, does. Kyojuro see's potential in Tanjiro and because he has no successor he trains Tanjiro in the art of flame breathing. Nezuko will be dead(by tanjiros hands). Sorry not sorry(?)

Instead of his younger sister Nezuko being turned into a demon, it was Tanjiro who was transformed. And meeting one of the strongest demon as a mentor. Part.
